Central atom: C (EN = 2.5) is less electronegative than O (EN = 3.5) so C is the central atom.
Formaldehyde, CH2O, is used as an embalming agent. Draw the structure of CH2O including lone pairs.
1. Click once on the grid, then just start drawing (dick, hold, and drag).
2. Double-click on a letter then type to change the atom label.
3. Click on a bond to cycle through single, double, and triple.
4. Use the lone-pair button to add lone pairs.
Note: after using the lone pair button, you will need to click on the bond button if you want to edit the bonds or atoms again.
